Monobutyl phthalate


Monobutyl phthalate is an organic compound with the condensed structural formula CH33OOCC6H4COOH. It is a white solid that features both an butyl ester group and a carboxylic acid group. It is the major metabolite of dibutyl phthalate. Like many phthalates, MBP has attracted attention as a potential endocrine disruptor.
MBP is also the secondary metabolite of butyl benzyl phthalate, less than monobenzyl phthalate. It hydrolyses to phthalic acid and 1-butanol.
